Okay, I can get to the end of Mission 3 where you have to face off against Killian in his ship but for the life of me I cannot beat him; either his damned missiles or his henchmen get me. Any tips or pointers, such as tactics or suggested weapons? Any help would be most appreciated.

Start the level with the Rocket Launcher (if you don't already have it, go to the bridge assault. Use your locktopus to open the weapon box in the armory and beat the level with it.) Play the level like normal, and when you run out of rockets, just drop it off and get another weapon. When you reach Killian, try to beat him with what you have, but if you die you'll start off at that point with the Rocket launcher. Hit one of his engines with all four rockets and he will die quickly and painlessly.

Actually as you're shooting the engines at one point the ship turns around and you'll hear Jack Dark saying things like "Here's your chance, hit him from behind." I figured out that you're supposed to shoot at the area where the door opens and he lets support on the ground.

you only need to destroy one engine, but watch out, if your shooting his left engine and he turns around, obviously youll now need to shoot at his right engine (because that is the left engine but backward)

*BUMP* just because I'm having the same problems with Kilian on Perfect Agent mode. I'm trying to get thru the levels using only the default items/weapons, and I'm doing pretty good up until I get to Kilian. I have a fully loaded D5, Magnum, and PSP (or whatever they're called..) and a full flak jacket and most of my health when I get to Kilian, but that Jack is pretty damn useless keeping the henchmen off my ass. I'm sure I could take Kilian out if it wasn't for those goons.

Unless you get the rocket via co-op wouldnt that take forever!? How would you possibly beat the rest of the level with a pistol?

Shoot only one engine. I repeat, do not waste your ammo trying to get both smoking.

I had one engine destroyed and the other was good as new and Killian just did a nose-dive into the shack I was hiding behind.

Very easy and simple. You take the P9P, shotgun and hawk. In that order. The P9P is more than good enough for the sniping in this level. The shotty is great for when you gotta get up close.

Once you get to Killian you simply wait until he flies over-head and unload as many shots with the shotun into ONE engine. Then when he flies up and shoots take cover and shot-gun the boxes with the SMG in them. You should be able to get one engine to little bit flaming.

The absolute second you expect he is gonna start dropping off troops you press down on the D pad and run across, dropping the shotgun and picking up the SMG.

Kill the two guys he has left for you either with your SMG if youre confident in your ammo(have at least 90 as the bottom number) or headshot with the P9P.

Now you only need 2-3 rounds with Killian before he's toast. Use the hawk to deal with his flame attack and missles. And take cover when he sprays turret fire. DO NOT try and hit him unless he is dropping off men.

When he drops them off, dont shoot or worry about the men. As long as you are on the opposite side from where you started Jack will handle them. Each dropoff you must unload one entire SMG clip into the same single engine youve been attacking since the beginning. I recommend zooming and clicking the trigger over and over to ensure accuracy.

Again, use the hawk for all fire/explosion attacks, and the SMG for all damage after the opening exchange where you got ONE engine to flaming.
